I just removed the fuel line from a 8hp kicker motor at the water separator. It had a line shutoff valve so I shut it off and cut the line. Couldn't pull it off. Now my starboard main 200 won't start! Is there some sort of vacuum now lost? I thought of trying the bulb to prime but it didn't sound like it was even trying to turn over. I want to remove the inline fitting from the separator but don't know what size the blocking plug would be. Don't want to buy a whole assembly but may have to. Somewhat corroded. Anyone know the size? I'm guessing 3/8.
